Step-by-step explanation:
Let (x, y) be the coordinates of point B.
(4, 6) => (-2, 4) => (x, y)
We have 2(-2) = 4 + x and 2(4) = 6 + y.
Solving these, we get x = -8 and y = 2.
Hence the coordinates of point B is (-8, 2).
To multiply 13.26 times 23, we first have to set it up vertically.
13.26
x 23
--------
3978
2652
----------
30498
Adding in the decimal, we get 304.98, because the total amount of decimal numbers in the equation, is 2. Therefore, the answer will have 2 decimal numbers. I hope this helps! :D But, if you don't understand how to multiply, tell me. I'm pretty sure that you do, but you know, just in case!
Answer:
The container can hold 18 gallons
Step-by-step explanation:
Assume the container can hold x gallons
∵ The container is
full with water
∵ It can hold x gallons
→ Multiply
by x to find the number of gallons in the container
∴ The number of gallons in the container =
x
∵ 4 gallons of water pouring out
∵ It is
full
→ Multiply
by x to find the number of gallons left in it
∴ The number of gallons left in the container =
x
→ The difference between the numbers of gallons is 4 gallons
∵
x -
x = 4
→ Subtract the terms of the left side
∴
x = 4
→ Multiply both sides by 9
∴ 2x = 36
→ Divide both sides by 18
∴ x = 18
∵ x represents the full of the container
∴ The container can hold 18 gallons
